Sensor Module Locations

NOTE: All IT modules are factory pre-configured and calibrated. All modules are tagged to indicate the
configuration including the sensor module number Identify all components during unpacking and install
using the factory configuration.
The gas sensor module utilizes a diffusion type sensor which should be located close to either the expected source or
destination of the gas hazard. If the gas is heavier than air, the sensor module should be installed within 24 inches of the
ground or floor. If it is lighter than air, move it above 6'.
After optimum locations are determined based on the above recommendations, consideration should be given to placing the
sensor modules in locations which are accessible for calibration service. Slight adjustments to the location of the sensor
module may have little impact on effectiveness but major effect on accessibility.
• Modules should be placed close to the potential source of gas.
• Modules should be placed in areas accessible for calibration.
• Sensors should be pointed down and the conduit should include an inverse trap to reduce moisture (condensation) from
accumulating in the electronics enclosure.
• Remote calibration fitting (5360-00) should be used to facilitate calibration gas delivery. Run polyurethane tubing (1/4"
O.D. x 1/8" I.D.) from fitting to an accessible location.
